REFRIGERANT CHARGING
WARNING:
This split system heat pump is shipped charged
with R410A refrigerant and ready for installation.
If repairs make it necessary for evacuation and
charging, it should only be attempted by qualified
trained personnel thoroughly familiar with this
equipment. Under no circumstances should
the owner attempt to install and/or service this
equipment. Failure to comply with this warning
could result in property damage, personal injury,
or death.
After refrigerant line connections are completed, it is
required that you leak check and evacuate the indoor
section and all line connections (using proper methods)
before finalizing the full system refrigerant charge.
• To achieve rated capacity and efficiency, the
compressor must be exposed to refrigerant for at least
24 hours prior to running and then the compressor must
be run for a minimum of 12 hours.
• Cooling mode charging charts and tables are applicable
only to matched assemblies of this equipment and listed
airflows for the indoor coil. Refer to the Quick Reference
Data sheet for additional charging information.
Outdoor units with non-AHRI listed indoor coils are not
recommended and deviations from rated airflows or
non-listed combinations may require modification to the
expansion device and refrigerant charging procedures
for proper and efficient system operation. For correct
system charging, refer to Figure 7 (page 10), Figure
8 (page 11), Figure 9 (page 11), Figure 10 (page
12), Figure 11 (page 12) and Table 5 (page 13),
Table 6 (page 13), Table 7 (page 14), Table 8
(page 14), & Table 9 (page 15).
• The refrigerant charge can be checked and adjusted
through the service ports provided external to the
outdoor unit. Use only gage line sets which have
a “Schrader” depression device present to actuate
the valve. A common suction port for heating mode
charging is included and located on the compressor
access panel above the outdoor unit service valves.
• Heat Mode Verification Tables are provided for quick
reference when the unit is in heating mode and for the
inspection of the liquid line pressures and temperatures.
See Table 10 (page 17), Table 11 (page 17),
Table 12 (page 17), Table 13 (page 18), & Table
14 (page 18).
• A high-pressure switch is factory-installed and located
in the compressor discharge line internal to the
outdoor unit. The switch is designed to de-energize
the system when very high pressures occur during
abnormal conditions. Under normal conditions, the
switch is closed. If the discharge pressure rises above
575 psig, then the switch will open and de-energize
the outdoor unit. The switch will close again once the
liquid pressure decreases to 460 psig. Please note that
the switch interrupts the thermostat inputs to the unit.
When the switch opens and then closes, there will be
a 5 minute short cycling delay before the outdoor unit
will energize.
Charging the Unit in AC Mode
(With Outdoor Temperatures Above 65° F)
1. With the system operating at steady-state, measure
the liquid refrigerant pressure (in psig) at the outdoor
unit service valve.
2. Measure the liquid refrigerant temperature (in
Fahrenheit) at the service valve.
3. Determine the required liquid refrigerant pressure from
Figure 7 (page 10), Figure 8 (page 11), Figure 9
(page 11), Figure 10 (page 12), & Figure 11 (page
12).
• If the pressure measured in Step 1 is greater than
the required liquid refrigerant pressure determined in
Step 3, then there is too much charge in the system.
Remove refrigerant and repeat Steps 1 through 3
until the system is correctly charged.
• If the pressure measured in Step 1 is less than the
required liquid refrigerant pressure determined in
Step 3, there is too little charge in the system. Add
refrigerant and repeat Steps 1 through 3 until the
system is correctly charged.

Application Notes & Charging Charts (Cooling Mode Only)
• This equipment’s cooling system contains refrigerant under high pressure. Always use safe and
environmentally sound methods when handling refrigerant handling or servicing the unit. Review the
factory literature and safety warnings prior to servicing.
• When repairing system leaks, always use a nitrogen (inert) gas to protect the refrigerant system and pressure
check the repair before re-charging. Always replace the filter-dryers when performing any repair to the refrigeration
system with one capable of acid removal. After completing the repairs, evacuate the system to 350 - 500 microns
and weigh in the refrigerant to the amount specified on the unit rating label.
• Charging charts are valid for a variety of indoor, return air conditions and are most influenced by the outdoor
ambient temperature, outdoor fan operation and the unit operating voltage. Before using these charts, make sure
the unit is in a stable operating mode. As shown in the charging charts: Figure 7 (page 10), Figure 8 (page
11), Figure 9 (page 11), Figure 10 (page 12), & Figure 11 (page 12), the ideal system sub-cooling can
vary over the range of operation. Reference the charts to determine the ideal amount of sub-cooling for a given
liquid pressure. Units charged to other values will not perform at the rated unit efficiency (EER) or rated Coefficient
of Performance (COP) in heating mode.
• To inspect a systems operation using quality instruments, match the measured liquid temperature to the units
chart. The measured liquid pressure reading should be within 3% of the charts value for most installations.
• For systems that are operating with more than a 5% deviation, inspect the unit for the proper voltage and phase
balance and the refrigeration system for leaks.
• Units that are operating at less then 95% of the nominal voltage or with a 2% phase imbalance may see a more
significant deviation than the amount stated above.
• DO NOT use the charts in systems that have a fan cycling under low-ambient control. Refer to the low-ambient
kit instructions for more information (If applicable).

Application Notes & Heat Mode Verification Tables (Heat Mode Only)
• Read all notes and warnings for the Cooling-mode
charging charts prior to using these Heating-mode
charge verification charts. Always use safe and
environmentally sound methods when handling
refrigerant handling or servicing the unit. Review
the factory literature and safety warnings prior to
servicing.
• When repairing system leaks, always use a nitrogen
(inert) gas to protect the refrigerant system and pressure
check the repair before re-charging. Always replace
the filter-dryers when performing any repair to the
refrigeration system with one capable of acid removal.
After completing the repairs, evacuate the system to
350 - 500 microns and weigh in the refrigerant to the
amount specified on the unit rating label.
• Before using the heat mode verification tables,
determine the outdoor ambient temperature and the
return air temperature to the unit. Locate the appropriate
location on the units verification chart based on those
measurements to determine the ideal discharge
pressure and temperature. See Table 10 (page 17),
Table 11 (page 17), Table 12 (page 17), Table 13
(page 18), & Table 14 (page 18). Verify the outdoor
fan and compressor are running and the outdoor coil
is free from frost accumulation. Also verify the system
is not operating in defrost mode before inspecting the
system.
• Always use quality instruments that are in good working
order to measure the actual operating point of the
refrigeration system. The discharge temperature should
be within 2 degrees of the ideal value and the pressure
should be within 2%.
• The most reliable way of verifying the system is at the
correct charge is to evacuate the system and weigh
in the charge to the amount shown on the rating label.
However, if an inspection with these verification charts
does not line up with the values shown and the ambient
temperature is above 50˚ F, then a more accurate
way to inspect the system for proper charge is with
the cooling mode charging charts. Switch the unit into
cooling mode and allow it to operate and stabilize for
a few minutes then inspect the unit operation with the
cooling mode charts and procedures.
Before changing the unit charge, always inspect
the following items first:
1. Inspect the liquid line temperature on the inlet and outlet
of the filter dryers. If it is the factory dryer and in good
condition there should be no temperature difference.
If the temperature difference is larger than 5˚, replace
the filter dryer with one that is bi-directional and has
acid removal capability. Refer to the unit RPL for the
recommended part number and size.
2. Inspect the units input voltage. Units operating at less
than 95% of the nominal voltage may deviate more
from the chart then previously stated.
3. Inspect the input voltage for a phase imbalance. Units
with greater then a 2% disparity will not operate at the
rated performance.
4. Verify that the unit filters are installed and are clean.
The pressure drop across the filters should not exceed
0.08 in-W.C.
5. Inspect the indoor coil, indoor blower and blower motor
for cleanliness, clogging, and proper operation.
6. Inspect the system for leaks. If any leaks are detected,
repair them immediately. Re-inspect the return air and
ambient temperatures and verify that the correct system
point on the verification chart was selected.
DO NOT use the charts in systems that have the fan cycling
under a low-ambient control. Low-ambient controls are
for cooling operation. In heating mode, the low ambient
control should be disabled. Unless the unit is in defrost
mode, the outdoor fan should always operate in conjunction
with the compressor.
IMPORTANT NOTE:
If the unit is equipped with a liquid valve with an
outdoor restrictor as shown in Figure 2 (page 4),
then it is not possible to measure the liquid pressure.
To approximate the liquid pressure, subtract 7 psig
from the discharge pressure.
Shaded boxes indicate flooded conditions.
Rated design values. The suction pressure will vary from design value if outdoor air flow, entering dry
bulb, or entering wet bulb temperatures vary.
1. All pressures are listed in psig and all temperatures in ° F
2. Discharge temperatures greater than charted values indicate an undercharged system.
